The first step for Moen Posi-Temp shower valves is to see what pipe is required for the tub trim kit. In this example we needed copper.

Solder copper pipe apart from the Moen valve, that way the internal parts won’t be harmed by the MAP gas flame.

PEX can be used with this Posi-Temp valve for the cold and hot water supplies as well as the shower water supply.

Set the Posi-Temp valve to the correct depth, otherwise it won’t look right with the finished wall.
